This went relatively quick as the space is roughly 20 sq. ft.
I minimized my joints by using the largest possible pieces. As expected this required me to cut into more full size sheets and leave a lot of extra waste.
I had a bit of a blowout around the water supply lines since the pipes don’t project perfectly perpendicular from the wall. Once the drywall was fully in place the blowout lays flat and will easily be fixed and hidden behind the vanity. Could have made the holes a 1/2″ larger in diameter, maybe next time.
